Answer:
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
= 0
θ =
arctan( ΔY )
ΔX
= 0°
ΔX = 6 – 2 = 4
ΔY = -3 – -3 = 0
Distance (d) = √ΔX2 + ΔY2 = √16 = 4
Equation of the line:
y = 0x – 3
When x=0, y = -3
Answer:
By simplifying the expression we get
4/3
If you buy 4 shirts you get
50 × .10 = 5
5 dollars off. So you pay
50 - 5 = $45
If you buy 8 shirts (4 shirts twice) it will be
45 × 2 = $90
Answer:
<h2>x = -8 and y= 0 → (-8, 0)</h2>
Step-by-step explanation:
The differences between f(x) values are 3, 6, 9, 12. The differences between those are constant: 3. When "second differences" (for uniformly spaced x values) are constant, the function is quadratic.
_____
The degree of the function is equal to the level of differences that are constant. Linear (1st-degree) functions have 1st differences that are constant; cubic (3rd-degree) functions have 3rd differences that are constant.
If each level of differences increases in the same way, the function is exponential.
